Introduction





E
veryone
met
at
the
ONR Station
parking lot
in
Kapuskasing
,
after a brief
discussion on the scopes of the projects
, detailing that the work is to be
completed this year and that any questions that arise after today’s site

meeting are to be posed to Bonnie Hummel as per the tender package
,

we
then proceeded
to the west end of the bridge at 69.7 Kapuskasing
.

We
parked in a small area off of Hwy 11, to the North of the tracks. There is a
similar parking area to the east of the bridge at 69.6 Kapuskasing. The two
bridges 69.6 and 69.7 fall within the yard limits at Kapuskasing. These
locations require a diffe
rent form of protection than the mainline. Train or
hi
-
rail vehicle movements can occur at any time, however they must travel
at such a speed

that they can stop before the bridge. An ONR flagman will
be present on site at all times for the contractor. T
he trains are scheduled
as per the Appendix 4 in the tender package, however work trains can
occur at any time. The Contractor can request work blocks from the ONR

ACTION BY:




flagman which will shut down the track over the bridge, but these must be
requested ahead o
f time and may be denied due to required train traffic.





The scope for 69.6 and 69.7 Kap is basically to install walkways, hand
railings, fibre
-
optic brackets and clean the bridges
.

It was mentioned that
an addendum would be put out asking the contract
ors for a price to install
the refuge bay ties (19’ long ties which would replace existing ties). The
ONR would provide guidance for the first couple of tie installations if the
contractor requests it. For 69.7 there will be 4 ties to change out and at
6
9.6 there are 2 ties 19’ ties to change out. The 16’ ties the 19’ ties replace
will need to be re
-
located on the bridge to support the new walkway
grating. The contractor may also have to shift ties for access. The
contractor will have to move the fibre
-
optic cable to install it in the new
brackets. This must be done under the supervision of Onterra. They can be
contacted through the ONR flagman on site.


The contractor is to dispose of the old timber walkway planks and hand
railing. Any leftover trac
k ties are to be stacked near the bridge in a
location approved by the flagman. When removing the existing hand
railing, workers will need to be tied off.
One possible option is the use of a
rail slider. It is an anchor that clamps on the rail to provid
e a tie of point
and it can slide along the rail to travel.


For the cleaning, in lieu of vacuuming, it is possible to fully enclose the
bridge so that all materials will be captured and removed. A procedure and
drawings for this will need to be submitted

and reviewed by the ONR. It
was noted that cleaning wasn’t on the schedule of prices, this will be added
in an addendum.


The 3 embedded ties that serve as the walkway approaches are to be lifted
so that the grating will come off the bridge level. This
may require some
digging out of the ties and shoring up the embankment under the ties to
provide full support.


This work can be performed in the winter.


There is a track switch at the east of the bridge at 69.6 Kap. The contractor
is not to touch this
switch. If it is to be changed for any reason, the ONR
flagman is the only person who can do this.


The ONR cannot supply any hi
-
rail vehicles to the contractor. There are
firms that rent them. Lecours is the closest with dealerships in
Kapuskasing and
Hearst. There is also Hi
-
Rail leasing out of Elliot Lake.


The bridge at 69.7 has a high water level under the bridge, this may affect
the access to the bridge. There are gaps on the piers between the girders of
the bridge which will allow access into th
e middle of the spans, but it is
tight.


If the contractor wishes to attach scaffolding or anything to the
bridge structure it must be

submit
ted
for ONR review.

ITEM

ACTION BY:





It was mentioned to the contractors that the ONR has a policy that if an
individual stays b
etween the rails on a bridge, then a harness would not be
required.


Everyone then drove to the bridge at 52.4 Kap and parked in a vehicle turn
-
around on the north side of Hwy 11, a few hundred feet east of the bridge.
There is a road crossing approximate
ly 500’ east of the bridge.


It will be required to survey the bridge to determine the proper thickness of
steel shims to be placed under the bearings. The contractor is to submit the
survey results in a drawing to allow the determination of the proper
el
evations based on the track profile.


The drawings show jacks to be installed under the main girders infront of
the bearings to lift the span. Hardwood timber blocks would be needed
between the top and bottom flanges to protect the bottom flange from bein
g
bent by the jacks. The contractor can propose alternative jacking schemes.
Spikes holding the rail would need to be loosened to allow jacking of the
span. It was measured and it was found that there are 7” from the
underside of the steel girders to th
e bridge seat.


On the drawings it is shown that the steel shims and neoprene pads are in
two pieces. This is to allow installation of the shims and pads in the
narrow space between the jacks and the anchor bolts.


It was noted that the right of way for t
he ONR track is generally 49.5 feet
on both sides of the centerline of the track.


Lastly, everyone drove to 95.0 Kapuskasing. Most people parked near an
old road crossing about 400 feet west of the bridge.


After arriving at the bridge, it was found that

there are additional reduced
rivets that could be replaced by bolts. An addendum will increase the
projected total of rivets to replace. It was also found that the Original
Detail “2” would need to be modified and applied at all floor beam
locations. A
dditionally, one additional Detail “1” will be required. The
drawing will be modified and re
-
issued under an addendum for this. The
new Detail “2” will include some cleaning and painting at all floor beam


girder connections.



The abandoned crossing 40
0’ west of the bridge could be rebuilt by the
contractor. The ONR could install some timbers to create a temporary
crossing to allow hi
-
rail vehicles on the track.


It was emphasized that all questions other than at this site meeting, were to
be sent to B
onnie Hummel
-
Clair in ONR procurement. It was also stated
that the expected train times are shown in Appendix
4

and that an ONR
foreman will be there at all times to clear for trains.

It is the responsibility

the bridge, however the ONR will always have someone on hand to protect
them from train traffic.



Frequently asked questions
:


Q


The tender mentions and 8 & 6 work schedule, how rigid is that
?

ng the
bridge or pouring concrete.


Q


Can the contractor
install a hand railing on the bridge deck for safety
?

A


Yes
.


Q


Where can contractors store equipment?

A
-

Anywhere on ONR property that is outside of the track clearance (10’
from the rail) an
d is flat.
